•
Open the test gas cylinder valve to let test gas flow over the sensor.
−
The currently displayed measured values start to flash.
The flashing stops after a static measured value has been reached.
−
The calibration is now carried out automatically.
−
The displayed measured values change to the values according to the gas supplied.
−
The automatic stability monitoring can be overridden by pressing the OK key. A ca-
libration then takes place immediately. If it is detected that no test gas has been ap-
plied, the 1-button calibration will be aborted. The channels will then indicate » n/
a «. If only one sensor is taking part in the 1-button calibration, a calibration will be
performed in each case when the OK key is pressed.
When the calibration is completed
and the displayed measured values
have stabilized:
−
The display containing the current
gas concentration changes with the
display » OK «.
•
Press the key or wait for 5 se-
OK
conds to quit the calibration.
−
The device changes to the measuring
mode
•
Close the test gas cylinder valve and
remove the device from the calibrati-
on cradle.
If a fault occurred during the 1-button
calibration.
−
The fault message »
and » « is displayed for the res-
pective sensor instead of the measu-
red value.
•
In this case, repeat the 1-button calib-
ration or carry out a single gas calib-
ration, refer to page 42.
•
If necessary, replace the sensor,
page 49.
